Well, yes. It depends entirely on the composition of the family income overall. First of all, single women and single parents will get absolutely no benefit from income splitting, which is a $2 billion program for 2015. Secondly, unless they're in the top 15% of income earners, they will not get anywhere near a fair share of tax benefit from income splitting.
At the same time, the repeal of the child tax credit has taken approximately $2 billion out of the hands of parents, many of whom are single parents, so the whole tax transfer system as it pertains to taxation within the family is pushing the very women that the government says it's so concerned about further back into the pack, as they attempt to just maintain some sort of an affordable income coming into their household. In after-tax terms, income splitting has taken that group of women a step backwards.
At the same time, this expectation that was just referred to, where young girls perhaps don't plan for higher incomes in the same way that young men do, means that the income-splitting tax benefits will actually encourage young women and women graduating from college to pay even less attention to their salaries, because they will know and will have discussed with their peers, their spouses, and their partners that in fact their paid work is perhaps worth more to the family when it's replaced with unpaid work. So while the whole country is working at trying to get women into better employment situations, we're now using tax subsidies to get them to not work.
